Page 11 reverse from Codex Magliabechiano, showing four day-symbols of the tōnalpōhualli: (ce = one) Flint/Knife tecpatl, (ōme = two) Rain quiahuitl, (ēyi = three) Flower xōchitl, and (nāhui = four) Caiman/Crocodile (cipactli), with Spanish descriptions.

The tōnalpōhualli (Nahuatl pronunciation: [toːnaɬpoːˈwalːi]), meaning "count of days" in Nahuatl, is an Aztec version of the 260-day calendar in use in pre-Columbian Mesoamerica. This calendar is neither solar nor lunar, but rather consists of 20 (veintenas), 13-day (trecenas) periods. Each trecena is ruled by a different deity.

Description[edit]

Tonalpōhualli calendar representation

The basis of the tōnalpōhualli is unknown. Several theories have been advanced for this calendrical period: that it represents a Venusian cycle, that it represents the human gestation period, or that it represents the number of days between the zenithal passage of the sun in the tropical lowlands. On the other hand, some scholars including J. E. S. Thompson suggest that the tōnalpōhualli was not based on natural phenomena at all, but rather on the integers 13 and 20, both considered important numbers in Mesoamerica.

The other major Aztec calendar, the xiuhpōhualli, is a 365-day year, based on 18 months of 20 days and five nameless days. A xiuhpōhualli was designated by the name of its first tōnalpōhualli day. For example, Hernán Cortés met Moctezuma II on the day 8 Wind in the year 1 Reed[citation needed] (or November 8, 1519 in the Julian calendar[1]).

The xiuhpōhualli and the tōnalpōhualli would coincide approximately every 52 years.
